This modern, contemporary-looking shrub is grown for the rich copper-red, architectural foliage. Almost by surprise, clusters of dainty white flowers with a hint of pink appear during early summer, giving contrast to the dark foliage. Glossy red seed heads follow, persisting well into autumn.

Physocarpus opulifolius 'Diablo' is a stunning addition to the shrub border. It looks particularly good partnered with a range of colourful foliage shrubs, such as Berberis, Elaeagnus and Euonymus. Height: 150cm (59"). Spread: 150cm (59").

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

Plant Physocarpus in a fertile, moist, well-drained soil in full sun or semi-shade. Physocarpus plants prefer an acid to neutral soil, but will tolerate more alkaline soils, although may they may become chlorotic in very chalky areas. Incorporate organic matter such as well-rotted manure or compost into the soil prior to planting.

Water regularly throughout the growing season until young Physocarpus plants are fully established. In spring, apply a mulch of well rotted manure or compost to the base of the plant. After flowering, cut back the flowered shoots to a healthy pair of buds, unless seedheads are required for late season interest.

Physocarpus opulifolius tolerates fairly hard pruning and may be cut back by half every few years to maintain a smaller size. On mature plants cut back about one quarter to one fifth of the oldest shoots to their base, to promote strong new growth.
